Lesnar, St. Pierre retain ultimate fighting titles

LAS VEGAS - Brock Lesnar defended his heavyweight title in his uniquely brutish style at UFC 100 last night, capping the sport’s landmark weekend with a second-round stoppage of Frank Mir.

Georges St. Pierre defended his welterweight title with a showcase of his inimitably well-rounded mixed martial arts skills in an unanimous decision over Thiago Alves, while Dan Henderson knocked out Michael Bisping with a single punch in a middleweight upset as the UFC rolled its odometer into triple digits on a celebratory night for the proliferating sport.

Lesnar (4-1) ended the main event with a relentless series of right hands into the face of Mir, who handed Lesnar his only loss nearly 18 months ago.

Lesnar, a hulking former pro wrestler with a mercurial temperament, then taunted his opponent while Mir still was on the ground. He added a two-handed obscene gesture to the booing sellout crowd at the Mandalay Bay Events Center.

There were no theatrics or poor sportsmanship from St. Pierre, the classy Canadian star considered the UFC’s pound-for-pound best. He was the superior fighter from the start, steadily punishing Alves with punches, kicks and repeated takedowns in his third title defense.

The 100th showcase was broadcast live in 75 countries, and thousands of fans without tickets for the event packed into closed-circuit shows all along the Strip.
